The actress went incognito in a pair of massive shades and a hat as she arrived at the airport on Los Angeles.

The star, who plays Anastasia Steele in the sexy flicks, showed off her new shorter hair do after chopping off her locks last month.

She teamed her low-key look, which was understandably comfy for her flight, with a pair of black jeans, striped T-shirt and a denim shirt.

It has been claimed Dakota and fellow Fifty Shades star Jamie Dornan, who plays billionaire S&M enthusiast Christian Grey in the big-screen adaptations of the erotic novels, haven't signed on to star in a spin-off.

But a source told The Hollywood Reporter that 33-year-old Jamie and 25-year-old Dakota, are currently only contracted to appear in three films based on the trilogy, so there are no guarantees they will star in a future adaptation of the upcoming novel.

The insider also claims that neither of the stars had any idea that another book, which would likely serve as the fourth film in the franchise, was even being written.

While Universal declined to comment on plans for the project, the source claims the 'Grey' movie will more than likely go ahead since the first film generated $570 million at the box office worldwide.

The second film, 'Fifty Shades Darker,' has yet to begin filming, but is already scheduled to be released on February 10, 2017, while the third film, 'Fifty Shades Freed,' is set to be released on February 9, 2018.

Northern Irish heartthrob Jamie was previously forced to deny rumours he was planning to quit the risky films.

He said: "The idea was that we honour the trilogy and do all three [movies]."

Asked whether his wife, Amelia Warner, was keen for him to quit the role because of the explicit sex scenes, he replied: "Total b*****ks!"
